Name of the Vulnerable Software and Affected Versions Linux kernel with VDUSE backend (affected versions not specified)

Description A flaw was found in vDPA with VDUSE backend. There are currently no checks in VDUSE kernel driver to ensure the size of the device config space is in line with the features advertised by the VDUSE userspace application. In case of a mismatch, Virtio drivers config read helpers do not initialize the memory indirectly passed to vduse vdpa get config() returning uninitialized memory from the stack. This could cause undefined behavior or data leaks in Virtio drivers.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
